Inventor: INIOTAKIS NICOLAOS
IPC: C01B4/00
Filed: 1981-06-16
Abstract: A process for the incremental enrichment of deuterium and/or tritium in a material which is suitable for the isotope exchange of deuterium and tritium with hydrogen, and an arrangement for the implementation of the process. The process and arrangement for the enrichment of deuterium and/or tritium in water which, in addition to a high transport speed for the molecules which participate in the isotope exchange, evidences a high enrichment factor for each enrichment stage and a high yield, so that at a relatively small number of stages and low energy consumption there is attainable an overall high degree of enrichment. For each enrichment stage, water containing deuterium and/or tritium is introduced into a carrier gas flow, reduced and set to a hydrogen (H2) partial pressure of maximally 100 mbar. Subsequent thereto, the carrier gas flow is conveyed along the primary side of an exchange wall which is suitable for the permeation of hydrogen, along the secondary side of which there flow a further carrier gas flow which contains a material adapted for the isotope exchange of deuterium and tritium with hydrogen in the gas phase thereof. The hydrogen isotopes deuterium and/or tritium which permeate through the exchange wall, after the isotope exchange, are bonded with the material in reaction product.

Title: Autodynamic pulse compound generator for the production of mechanical energy
Inventor: WOLLNY ARNOLD
IPC: F03G3/00
Filed: 1981-11-04
Abstract: The invention relates to an autodynamic pulse compound generator for the production of mechanical drive power, to be operated independently of conventional types of fuel. The areas of application lie in the field of industrial electrical power generation and in that of ocean-going ship propulsion. According to the invention, the autodynamic pulse compound generator is driven by accelerated rotating pulse gravitational masses, in the direction of rotation of the rotor, only in the earth direction, by means of actuated acceleration pistons, and is then converted into usable drive force by way of the media of the kinetics employed and the articulated lever and gravitational effect of the individual pulse weights. The compression operation and the solenoid control of the acceleration pistons are performed by a unit built into the rotor, with simultaneous driving of these units by a part of the generated drive power of the rotating pulse compound generator. By the combined use of a plurality of pulse compound generators, which act on a torque shaft, the power output can be increased in such a way that current-producing generators of power station size can be operated. By means of this power technology, the use of autodynamic pulse compound generators opens up the possibility of unlimited electricity generation totally independently of all types of primary energy raw materials and consequently free of exhaust gases.
